Adsorption performance of zero-valent iron-loaded biochar for tetracycline antibiotics.

ABSTRACT: Tetracycline hydrochloride (TCH) and oxytetracycline hydrochloride (OTC) are widely used tetracycline antibiotics in global livestock production and the medical field. However, due to their strong chemical stability and resistance to degradation, these antibiotics can cause severe environmental pollution. Adsorption technology is an effective method for removing these drugs from wastewater. In this study, hexahydrate ferric chloride (FeCl₃·6H₂O), 2-methylimidazole (C₄H₆N₂), and potassium hydroxide (KOH) were used to modify biochar (BC) derived from Camellia seed shells, enhancing its adsorption performance for the TCH and OTC. The adsorption process primarily involves chemical adsorption and multilayer adsorption mechanisms. Sol
